**Problem Statement:**A chemist prepares a solution of magnesium fluoride (MgF₂) by measuring out 0.0152 μmol of magnesium fluoride into a 200. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's magnesium fluoride solution. Be sure your answer has the correct number of significant digits.**Solution Explanation:**1. **Convert Micromoles to Moles:** \[ 0.0152 \, \mu\text{mol} \times 10^{-6} = 0.0152 \times 10^{-6} \, \text{mol} = 1.52 \times 10^{-8} \, \text{mol} \]2. **Convert Milliliters to Liters:** \[ 200. \, \text{mL} = 200. \times 10^{-3} \, \text{L} = 0.200 \, \text{L} \]3. **Calculate the Molar Concentration:** \[ \text{Concentration} (C) = \frac{\text{Amount of Substance (mol)}}{\text{Volume of Solution (L)}} = \frac{1.52 \times 10^{-8} \, \text{mol}}{0.200 \, \text{L}} = 7.6 \times 10^{-8} \, \text{mol/L} \]**Final Answer:**The concentration of the magnesium fluoride solution is \(7.6 \times 10^{-8} \, \text{mol/L}\).**Diagram Explanation:**The diagram or image provided represents a textbox for inputting the calculated concentration value in mol/L.- The textbox is labeled with "mol/L" indicating the units for the concentration.- There are additional options for formatting numbers with scientific notation (indicated by the "×10" button), clearing input (the "X" button), and seeking help or guidance (the "?" button).

Given that, Moles of MgF2 added to 200 mL(= 0.2 L) flask = 0.0152 µmol = 0.0152×10-6 mol

A chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 8.200 g • She put some solid sodium hydroxide into the graduated cylinder and weighed it. With the sodium hydroxide added, the cylinder weighed 45.74 g- • She added water to the graduated cylinder and dissolved the sodium hydroxide completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 24.09 ml. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. ml
